UC2843AN Overview


This switching controller fits most application requirements since it is packaged in a 8-DIP (0.300, 7.62mm) package. dc motor controller is suitable for 1 output generation. Tube is the solid enclosure in which PMIC is packaged. A total of Transistor Driver dc switching's outputs can be handled by it. A 7.6V~30V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~85°C TA rating. The switching controller is capable of switching at the Up to 500kHz position. The Through Hole value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. An array of 8 terminations of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. You can find other relevant dc to dc converter ics by searching "UC2843". Switching converter has a total of 8 pins. The type is a particular Switching Regulator or Controllers of switching converter. Statistically, DC regulator outputs 15V volts. A starting point for a project is to note down the dc dc regulator's usual output current, which is 1A. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. 500kHz is the frequency of the switching controller. Input voltage can be set to 25V for nominal working status. The supply voltage should be 11V. Current supplied to the controller should not exceed 25mA. 11mA current flow input could satisfy the switching converter for operation.
